To all whom 'tt may concern:

Be it known that I, GEORGE H. BAILEY, a resident of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Tanks for ater-Closets, &c., of which the following is a specification.

This invention relates to flushing and other water containing tanks, and more particularly to flushing tanks for water closets and the like.

The object ,of the invention is to provide a tank constructed of sheet or other metal and provided with means for conducting away the condensation due to the sweating of the tank.

Flushing and similar tanks constructed of metal and enameled are sightly and sanitary but are objectionable on account of the dripping due to sweating or the condensation of moisture on their outer surfaces. Various constructions have been devised to avoid sweating or take care of the condensation.

The present invention has for its object a tank of the character named provided with means for conducting away the condensation due to sweating and which is of simple, cheap and practical construction.

The invention comprises a tank and associated parts such as hereinafter described and claimed. k

In the accompanying drawings, Figure 1 is a horizontal section of the tank on the line 11, Fig. 2; Fig. 2' is a vertical transverse section through the same on the line 2-2, Fig. 1; Fig. 3 is a vertical sectional View at the flushing outlet on an enlarged scale; and Figs. 4 and 5 are vertical sec tional views showing modifications.

The tank may be of any suitable shape and size, but preferably is rectangular with rounded corners as is the usual construction of flushing tanks. It may be of porcelain or cast iron, but preferably is, as shown, of thin sheet metal. It has a front wall 1, end walls 2, rear walls 3, bottom 4 and cover, not shown. The body may be formed in.

any suitable way, but preferably has the collect the" condensation.

brazing, but preferably by welding, the welded oint being as shown at 5.

The top edge'of the tank is strengthened and reinforced by curling the same over to form a bead 6, or in any other suitable way such as described in. my application filed May 23, 1908, Serial No. 434,618.

The tank will be provided in its bottom or elsewhere with the usual openings for .sightly finish. In order to take care of the condensation on the surface of the tank due to sweating I provide the tank around its bottom with suitable trough or gutter 8 to As shown, this gutter is'formed by curving the lower edge of the front and end sheet outwardly, but if desired said trough or gutter may be formed from a separate piece suitably secured to the bottom edge of the tank. This trough or gutter may be more or less open at the top and is entirely coated with the enamel both outside and inside. If the condensation is sufficiently heavy to trickle down the wall of the tanks it is caught and collected in this gutter.

To conduct away the condensation from the gutter there is provided underneath the tank a suitable plate or pan 1l.which is held in proximity to the bottom of the tank and spaced therefrom so as to provide an air space and also'to collect the condensation forming on the bottom of the tank. This plate or pan can be conveniently held in position by being clamped between the two nuts 12 and 13 on the flush valve fitting. This pan may project at one point out underneath the trough 8 and the latter provided with a hole 9 for the condensation to trickle down onto the plate or pan, as shown in Fig. 4., or a small tube 15 may lead from the trough inwardly above the pan as shown in Fig. 2. from the side faces of the tank finds its way to the pan or plate 11. To conduct the condensation from this plate or pan a suitable conduit is provided from the space above said plate to the outlet pipe, such as an opening or pipe 16 extending through the flush- In either event the condensation ing valve fitting, as shown in Fig. 3, and projecting into the space above the pan or plate 11. In order to prevent a rush of water through said conduit when the tank is being flushed, a suitable check valve, such as ball valve 18, is provided in said conduit or adjacent thereto, seating away from the outlet pipe and elIectually preventing the water from the flushin pipe passing through said conduit into the space above pain 11. but arranged to readily unseat or allou the condensation above said pan to pass into the flushing pipe.

in I 5 the pan 11 is omitted and a pipe 19 having on it the check valve 18 leads from the gutter S to the outlet pipe. A felt or other heat insulating lining 20 covers the bottom of the tank to prevent sweating on the bottom.

The tank described is of simple construction and provides means for effectually taking care of the condensation due to sweating by simple but. effective means.

What I claim is 1. A flushing tank composed of sheets of metal having its end and front walls and its bottom welded at the outer bottom corners and projecting outwardly at said corners to jorin a gutter at the lower ed es of its walls, and a drainage connection rom said gutter.

2. A flushing tank formed of sheet metal having its end and front walls and its bottom welded at the outer bottom corners and projecting outwardly to form a gutter at the lower edges of its walls, a flushing pipe connected to said tank, and a drainage passage from said gutter to said flushing pipe.

3. The combination of a flushing tank, apan underneath said tank in position to receive the condensation from the walls thereof but not projecting be ond the sides and ends of said tank, an out et pipe, and a drainage passage from said pan to said outlet pipe.

4. The combination of a flushing tank, a shallow pan underneath said tank in position to receive the condensation from the walls of the tank, an outlet pipe, a drainage passage from said pan to said outlet pipe, and a check valve in said passa e.

5. The combination of a ushing tank provided at the bottom of its walls with a gutter a pan underneath said tank, and a drainage passage from said gutter to said 6.,The combination of a flushing tank provided at the bottom of its walls with a. gutter, a pan underneath said tank, aflushing outlet from said tank, and a drainage passage from said gutter to said pan and from said pan to said flushin outlet.

7. The combination of a ushing tank provided at the bottom of its walls with a gutter, a pan underneath said tank, a drainage passage from the gutter to said pan, a

flushing pipe connected to the tank, a drainage connection between the pan and said flushing pipe, and a check valve in said drainage connection.

In testimony whereof, I have hereunto set my hand.
